Part Number: TPS65140-Q1 Other Parts Discussed in Thread: TPS65140 , TPS65131 Hi team,
My customer only uses the negative and positive charge pump and LDO for +18V and -11V. They don't need the boost converter output. But I see the SUP pin need to be…

After turning off, you need to wait for 2S, and you can output 12V normally after turning on. If it is turned off and turned on again immediately, the chip output is only 5V, which is the same as the input voltage. The normal voltage…
Part Number: TPS65140-Q1 Other Parts Discussed in Thread: TPS65140 , TPS65141 Hi, I am Hwadong Song of TOVIS
As I wroted in title, our tps65140 power circuit doesn't work well.
Specifically, the output is too low(0V or 7V). So could you check whether…

Could you please help recommend one appropriate device to support below LCD specs? VIN=VDD=3.3V, there are four output voltages as below.
Thanks & Best Regards…
Hello Cris,
I was on personal leave after assigning this thread and noticed that this was still un-answerd.
My apology but I am not sure if I understand your question. Are you suggesting that enabling the TPS65140 is causing P5V supply voltage to drop…
Part Number: TPS65140 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi Team,
My customer would like to confirm the loop stability on TPS65140, do you have any simulated tool (TINA or …) can share with us?
Thanks…
Part Number: TPS65140 Hi, I am Hwadong Song of TOVIS co. ltd. in Korea.
I am trying to apply tps65140 IC in our LCD module driving Board.
But in our circuit as attached file, the V03 voltage is not correct.
(Specifically, V03 is 0V, and other V01…
Hello Falko,
Thank you for noticing it and there does appear to be typographical error in that equation. It should be:
D=(Vout+Vd-Vin) / (Vout+Vd-Vsw) = (10+0.8-3.3) / (10+0.8-0.5) = 0.73
My apology about this and we will correct it in next revision…
